Скачать книгу - Fundamentals of the Physical Theory of Diffraction



The book is a complete, comprehensive description of the modern Physical Theory of Diffraction (PTD) based upon the concept of elementary edge waves. The theory is demonstrated with examples of the diffraction of acoustic and electromagnetic waves at perfectly reflecting objects. Readers develop the skills to apply PTD to solve various scattering problems. The derived analytic expressions clearly illustrate the physical structure of the scattered field. They additionally describe all of the reflected and diffracted rays and beams, as well as the fields in the vicinity of caustics and foci. Shadow radiation, a fundamental component of PTD, is introduced and proven to contain half the total scattered power. The equivalence relationships between acoustic and electromagnetic diffracted waves are established and emphasized. Throughout the book, the author enables readers to master both the theory and its practical applications. Plotted numeric results supplement the theory and facilitate the visualization of individual contributions of distinct parts of the scattering objects to the total diffracted field Detailed comments help readers understand and implement all the critical steps of the analytic and numeric calculations Problem sets in each chapter give readers an opportunity to analyse and investigate the diffraction phenomena

Brazilian Jiu-Jitsu: Theory and Technique Brazilian Jiu-Jitsu: Theory and Technique

Автор: Gracie Renzo, Gracie Royler, Danaher John

Год издания: 

During the last decade, the martial arts world has looked to innovative mixed martial arts competitions such as the Ultimate Fighting Championship to determine which fighting style is the best. These contests have repeatedly shown the grappling style of martial arts, headed by Brazilian jiu-jitsu, to dominate. The Brazilian jiu-jitsu style stems from the premise, garnered from analysis of actual street fights, that the outcome of any fight is decided on the ground. While most martial arts deal only with the initial punching and kicking stages of combat, Brazilian jiu-jitsu concentrates on ground combat. This guide shows how to use Brazilian jiu-jitsu to increase combat effectiveness. Photographs and step-by-step instructions show how to master the techniques used in this exciting new form of combat. Renzo Gracie, a two-time world Abu Dhabi submission jiu-jitsu champion, two-time Brazilian national champion, World Combat champion, and Martial Arts Reality Superfight champion, teaches Brazilian jiu-jitsu at an elite martial arts academy. Royler Gracie has competed in the Black Belt ranks for 20 years, winning the world title four times and the Abu Dhabi world submission championship for two consecutive years. They live in New York City.

Год издания: 

As part of the dynamics of international economic cooperation by the need for mutual settlement operations, so the problem of organization of settlements is an important place for the economically active subjects, especially in a globalized economic space in the functioning of transnational structures and scale of the export, import and international financial transactions. In agreeing on the order of calculations, the participants determined the form of payment in order to fulfill the financial obligations of the agreement – regulated by means of voluntary compliance through a credit institution liabilities, characterized by specific features on the order of transfer of funds to the account, a certain kind of settlement document, as well as office procedures. The source of payment relations is the need to have one contractor expressed in the appropriate disposition, the other in shortage. This relationship gives rise as a consequence of the relationship with the lending institution. Need to accession will intensify in the subjects of international payment relationship.
